l In the drawing:

Figure 1 is a perspective illustration of the bar head with a portion of the bar body f l *thefcable's '14an'cl ltarei placed' under proper tension substantial1-y"as shown iin iFigui-'e `f2.

The 2rodfb maynow be' conneated'to-l thve't'ow car 'and the'xtowing 'operation proceeded" with.

and kcables being shown.

`Figure 2 is ak plan view of the device in operative position'relative to a carpart brokenl away. p

Figure 3 is an enlarged transverse crosssection through thehead of the bar.

Figure 4 is an enlarged section on line l-4c of Figure 2- y Figure 5 is yan enlarged section on line Y 5 5 of Figure 2.

y'Referring now more particularly to the drawing, I show at 1.a tubular body portion having a threaded Vnut revolubly mounted v on one end as at 2.

At 3 I show an externally threaded tubular element adapted to engage the threaded Y nut 2 and pass into the body 1 as shown.y The element 3 is provided with a plurality of spaced oriices as 4. V A rod 5 is shown with an eye 6 formed on one end thereof, the other end slidablyengaging the element 3 and having an orifice as 7 formed therein so that a pin as 8a may be inserted" through" any'fgiven'forice1 in' element3`and orifice f7'to hold the fparts Sand 5 in fixed relation to eachfotherandf yet'f permittlongitudinal "adjustment thereof.

fOn' the end of the' body I portion l? remote i frominut 2 yare lmounted o'ppositel'y 'directed and radially arranged pins asf 8.

y The head y 9 is provided withrearwardly vextendlng and parallel arms 10 havinggpivota'l:v engagement with vthe "pins f8 f as shown.
